Microsoft also revealed that this free upgrade doesn’t just extend to the full version of Windows 10.

Like with Mac OS X, Windows 10 will bring tweaks and new features to its users via free software updates.

“With Windows 10, we think of Windows as a service,” explained Terry Myerson, Executive VP of Operating Systems at Microsoft. “You could comfortably think of Windows 10 as the world’s largest internet service.”

There’s no mention of when Windows 10, with its focus on offering a seamless Windows transition for users regardless of their device, will be released to consumers.

All we know so far is that Windows 10 will be released sometime this year.
